Question

我的php脚本在我的本地电脑上运行良好，但是当它们被上传到测试服务器时，它表现得异乎寻常。 我记得之前在测试服务器中运行过的脚本。

我对脚本进行了调查，并得出结论，每当我向任何 PHP页面提交POST值时，结果会抛出多余的字符，如下所示：

d

{ “成功”：1}

0

这是我用来测试POST的示例脚本，导致上述结果：

<?php
// Turn off all error reporting
error_reporting(0);
echo json_encode(array("success"=>1));

所以基本上，所有的帖子结果都会显示一行显示基数为16的回显字符计数，然后是实际回显输出，最后是另一行显示< strong>数字0 。

我在chrome的inspect元素和chrome的POSTMAN扩展中看到了带有不需要字符的结果体。这就是阻止我所有的ajax json依赖函数工作的原因。

这可能是服务器问题，但我不知道如何测试它以确认我的预感。

通过GET查看脚本（或在浏览器中输入网址）显示没有上述额外字符的预期{"success":1}。

任何帮助都将受到高度赞赏。谢谢！

修改

我使用的是Firefox，问题仍然存在。

根据请求，这是我使用的许多AJAX函数之一，它在我的测试服务器中不起作用，但在我的本地服务器中工作......

Answer 1

您在问题中描述的回复正文的格式特定于chunked transfer encoding。但它应包含标题Transfer-Encoding: chunked而不是Content-Length。

我知道这种行为的唯一可能原因是一个不了解HTTP 1.1的代理，并且没有按Transfer-Encoding标题所示解码响应主体。

标题Via表示请求（和响应）通过代理传递，但我无法判断是否应该指责UberGlobal-Cloud。

Answer 2

也许我的情况可以帮助某人。错误在于客户端对请求字符串的错误编码。我确实以 win-1251 编码发送了 json，因此服务器尝试将其视为 UTF8 并导致此类伪影。

Answer 3

首先包括header('Content-type: application/json'); 然后在浏览器中打开页面（因为你的脚本似乎不依赖于帖子变量）然后在浏览器中检查你的结果，如果它仍在那里那么检查服务器

PHP POST在结果正文之前和之后添加了其他字符
